Android Auto does not work with Mercedes Comand

I have tried both S10 and S21, they both keep frequently disconnecting from the car's head unit. I can't point to anything other than the operating system or the recent security patch.

Things I have tried:

  1. Made sure OS and all relevant apps are up to date.
  2. OEM cable and variety of other cables that work on other car head units including one which provides 10Gbps data transfer.
  3. Toggled on and off various settings in the developer options. Tried every default USB connection setting. Also tried USB debug.
  4. Cleared storage and cache of Android Auto, Google play services and Google app.
  5. Uninstalled all the updates for Android Auto and tried the base version after still not having luck.
  6. Wiped the phone and tried with only Android Auto installed alongside the preinstalled apps.
  7. Force stopped every app I saw in the Apps list.
  8. Tried different combination of settings in Android Auto.

The result is the same, the phone would completely disconnect from the head unit and try to reconnect again in a loop at a variable interval of 2-10 seconds.

Can someone please propose a solution as I'm left scratching my head on how Samsung's competent test team completely oversaw this bug?

After "blaming" all these issues on your phone/apps, I'd be investigating the possibility that my head unit is causing the problems, if I were you. It may well be that your HU requires a firmware update to stabilise its own OS. Call your Merc dealership for advice.

Do you mind sharing the software version of your command unit?

Already tried that. It works fine on other branded phones but not Samsung, which does not make it a good enough case for me to pay service cost for a diagnosis they can't fix, especially if the car's out of warranty. The head unit is already on the latest available software version as I was told

Having the exact same problem with my S21 ultra on a 2015 CLA. Can't seem to get it to stop disconnecting, tried multiple cables. Apple CarPlay works flawlessly which is extremely frustrating.

I had a look but can't seem to find the software version. Whereabouts in the settings is it and I'll have a look.
